The V550 is a 6U, one-slot VME module which will acquire position data from up to eight LVDT (linear variable differential transformer) position sensors. The LVDT sensors are excited by an ultrastable synthesized sinewave generator, and conditioned by a precision 16-bit A/D converter followed by digital signal processing. The resident microprocessor supervises scanning and signal conditioning, and places updated position data in VME-accessible dual-ported data registers for instant access from the VME bus.

LD2
-
A linear variable differential transformer (LVDT) is a type of electrical transformer/transducer used for measuring linear displacement (position). A counterpart to this device used for measuring rotary displacement is called a rotary variable differential transformer (RVDT). The RVDT is like an LVDT in that it measures a positional displacement, however, the displacement, which is still a linear proportional function, is based on rotary instead of linear positional movement.

Linear Variable Differential Transformers (LVDTs)
-
Whilst there are several ways to measure displacement, the Linear Variable Differential Transformer (LVDT) remains a popular transducer in most industrial applications. LVDTs initially were used as a means of taking dimensional readings in laboratories. They gained popularity in a wide variety of industrial monitoring and control applications, and whilst an LVDT is used to measure displacement the technology can be employed within other transducer types.

The Model 515 High Accuracy AC Reference Generator fills a need for a relatively low cost and practical solution for supplying a reference excitation to typical LVDT and Synchro/Resolver transducers. The Model 515 has built-in load sensing which, in effect, yields "zero" output impedance and virtually eliminates the effects of fluctuating output loads. With up to 15 VA of output into loads with as much as 80 of phase shift, the Model 515 is ideally suited to driving inductive loads.
